Cluster computing method for online emergency control strategy for transient safety stability of power system

The invention discloses a cluster computing method for an online emergency control strategy for the transient safety stability of power system, belonging to the technical field of emergency control of the power system. Computing of the online emergency control strategy is divided into the stages that the emergency control strategy for transient power-angle stability is first computed; and based on searched optimization control strategy, voltage and frequency of the emergency control strategy for the transient safety stability are computed. According to the above technical scheme, the online emergency-control optimization strategy for the transient safety stability of a large power grid can be rapidly searched.
